Aside from Gregg Popovich—who still works with a respected front office and robust scouting department—NBA coaches who are given general manager responsibilities almost always end up being bad at both jobs. It’s like cooking risotto on Top Chef. Everyone knows the history, everyone thinks they can pull it off, nobody ever wins. Stan Van Gundy was outstanding in Orlando; he left Detroit with Reggie Jackson still on the books for over $35 million. After years of never putting together a proper bench, Doc Rivers was stripped of GM duties in L.A.; last year he had arguably his best season as a coach since 2008.
